Description

This cmdlet contains more than one parameter set.
You may only use parameters from one parameter set, and you may not combine parameters from different parameter sets.
For more information about how to use parameter sets, see Cmdlet Parameter Sets (http://go.microsoft.com/fwlink/?LinkID=187810).

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; or a valid name of an Authentication provider (for example, MyAuthprovider1); or an instance of a valid SPTrustedIdentityTokenIssuer object.

Optional Parameters

-AssignmentCollection

Manages objects for the purpose of proper disposal.
Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management.
Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory.
When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store.
If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.
